Abstract

A method of detecting leaks on metallurgical vessels delivered with refractory material and equipped with cooling elements. Whereas major leaks can be detected by monitoring the flow quantities in the individual circuits of the entire cooling circuit of the furnace vessel, no method has so far been disclosed according to which even the smallest leaks, during which less than 250 cm<3> down to the quantity of a drop escapes, can be located. The method according to the invention is distinguished by the fact that cooling liquid escaping during a leak is collected as vapour and is fed to a moisture indicator and recorded. For this purpose, perforated vapour-collecting tubes (5) are installed below the cooling elements (3). A moisture indicator is attached to the outlet of each vapour-collecting tube (5) outside the furnace vessel (1). The method and device are suitable for electric-arc furnaces, reduction furnaces, etc. <IMAGE>
